The reference time is the time point when the air conditioner performs the filter screen cleaning last time. And after the standby time length of the air conditioner is larger than the first threshold value and the filter screen cleaning operation is finished, recalculating the standby time length. And recalculating the operation time after the operation time of the air conditioner is longer than the second threshold and the cleaning operation of the filter screen is finished.

By adopting the method for cleaning the filter screen of the air conditioner, which is provided by the embodiment of the disclosure, the air conditioner obtains the standby time and the running time. When the standby time length is longer than the first threshold value, the air conditioner is longer in standby time length, and the filter screen is in an unused state for a long time, so that dust accumulation occurs. And under the condition that the operation time length is longer than the second threshold value, the operation time length of the air conditioner is longer, and the filter screen is in a long-time use state, so that the filter screen is dirty and blocked. And under the condition that the two dirt blocks appear, the air conditioner executes corresponding filter screen cleaning operation according to the reference time of the last filter screen cleaning. The air conditioner can clean the filter screen in time in both the standby state and the running state, and the cleaning effect of the filter screen is improved. In addition, the corresponding filter screen cleaning operation is executed according to the last filter screen cleaning reference time, so that the problem that the time point of the air conditioner for cleaning the filter screen in standby and the time point of the air conditioner for cleaning the filter screen in operation are too close to each other, and the frequent filter screen cleaning of the air conditioner in a short time is avoided, and the energy consumption is too high.

In this way, when the time difference between the reference time and the current time is greater than or equal to the first difference threshold, it is indicated that the time point of the last screen cleaning of the air conditioner is far from the current time. And the air conditioner executes corresponding filter screen cleaning operation according to the time difference value. The problem that the energy consumption of the air conditioner for cleaning the filter screen is too large in a short time is solved, and the energy consumption of the air conditioner for cleaning the filter screen is reduced.

The time of the filter screen cleaning is adapted to the time difference value, and the filter screen cleaning effect is improved. Under the condition that the time difference is smaller than the second difference threshold, the time point of the last filter screen cleaning is relatively close to the current time point, and the filter screen cleaning is only needed to be carried out according to the first cycle rotation times. And under the condition that the time difference is greater than or equal to a second difference threshold, the time point of the last filter screen cleaning is relatively far from the current time point, and the first circulation rotation times are compensated through the circulation rotation times of the last filter screen cleaning, so that the target circulation rotation times are determined. And the air conditioner cleans the filter screen according to the target circulation rotation times. The filter screen cleaning time length and the time difference value are more adaptive, and the filter screen cleaning effect is improved.

In addition, the air conditioner executes corresponding filter screen cleaning operation according to the last filter screen cleaning reference time, so that the problems that the energy consumption of the air conditioner for frequently cleaning the filter screen in a short time is overlarge due to the fact that the time point of the air conditioner for cleaning the filter screen in standby and the time point of the air conditioner for cleaning the filter screen in operation are too close are avoided, and the energy consumption of the air conditioner for cleaning the filter screen is reduced.

Optionally, the preset conditions include: the absolute value of the difference between the operating parameter and the standard parameter is greater than the error threshold, or the ratio of the difference between the operating parameter and the standard parameter to the standard parameter is greater than the ratio threshold. The preset conditions are not limited to the foregoing two conditions, but may be other conditions capable of indicating errors of the operation parameter and the standard parameter, for example, an absolute value of a difference between the operation parameter and the standard parameter is greater than an error threshold and is maintained for a second period, or a ratio of the difference between the operation parameter and the standard parameter to the standard parameter is greater than a ratio threshold and is maintained for a second period, etc. Therefore, under the condition that the error between the operation parameter of the air conditioner and the standard parameter is large, the dirt degree of the filter screen can be timely judged through the operation parameter. The air conditioner can timely start the filter screen cleaning function under the running state.

Optionally, when the operation parameter of the air conditioner meets the preset condition, after the corresponding filter screen cleaning operation is executed according to the reference time, the air conditioner further includes: the air conditioner obtains new operation parameters after the filter screen cleaning operation is executed; and setting the new operation parameters as standard parameters when the new operation parameters meet preset conditions.

Thus, the air conditioner obtains new operation parameters after the filter screen cleaning operation is performed. If the new operation parameter still meets the preset condition, that is, the error between the new operation parameter and the standard parameter is still larger after the filter screen is cleaned, the new operation parameter is judged to deviate from the standard parameter because of other factors, for example, the new operation parameter may deviate from the standard parameter because of other reasons such as voltage fluctuation refrigerant loss. In order to avoid the condition that the running parameters meet the preset conditions when the air conditioner runs due to the problems, so that unnecessary filter screen cleaning operation is performed, the air conditioner takes the new running parameters as standard parameters, and continuous over-cleaning is avoided.

To avoid continuous over-cleaning. For example, after the air conditioner next acquires the operation parameters and the standby time period is 100 hours, the minimum interval between the cleaning of the filter screens is 100 hours.

Optionally, the air conditioner performs a corresponding filter screen cleaning operation according to the reference time, including: and under the condition that the time difference value between the reference time and the current time is greater than or equal to a first difference value threshold value, the air conditioner executes corresponding filter screen cleaning operation according to the time difference value. Therefore, the problem that the energy consumption of the air conditioner for cleaning the filter screen is too large because the air conditioner frequently cleans the filter screen in a short time is avoided when the air conditioner is in standby and when the air conditioner is in operation is avoided, and the energy consumption of the air conditioner for cleaning the filter screen is reduced.

Optionally, the air conditioner performs a corresponding filter screen cleaning operation according to the current state and the time difference, including: the air conditioner determines the first circulating rotation times of the filter screen corresponding to the time difference value according to the first relation; the air conditioner determines the first circulation rotation times as target circulation rotation times under the condition that the time difference value is smaller than a second difference value threshold value; under the condition that the time difference value is larger than or equal to a second difference value threshold value, determining target circulation rotation times according to the first circulation rotation times and the circulation rotation times of the last filter screen cleaning; and the air conditioner executes corresponding filter screen cleaning operation according to the current state and the target circulating rotation times. Thus, the first circulation rotation times are compensated by the circulation rotation times of the last filter screen cleaning, and the target circulation rotation times are determined. And the air conditioner executes corresponding filter screen cleaning operation according to the current state and the target circulation rotation times. The cleaning time of the filter screen is more adaptive to the current state and the time difference value, and the cleaning effect of the filter screen is improved.

Optionally, the air conditioner determines the target circulation rotation number according to the first circulation rotation number and the circulation rotation number of the last filter screen cleaning, including: the air conditioner determines the compensation circulation rotation times corresponding to the circulation rotation times of the last filter screen cleaning according to the second relation; the air conditioner calculates the sum value of the first cyclic rotation times and the compensation cyclic rotation times, and the sum value is determined as the target cyclic rotation times; wherein the number of compensated rotations is inversely related to the number of rotations of the last screen cleaning cycle. Therefore, the air conditioner compensates the first circulating rotation times through the compensating circulating rotation times, and cleans the filter screen according to the compensated target circulating rotation times, so that the cleaning duration and the time difference value of the filter screen are more suitable, and the cleaning effect of the filter screen is improved.

The time of the filter screen cleaning is adapted to the time difference value, and the filter screen cleaning effect is improved. Under the condition that the time difference is smaller than the second difference threshold, the time point of the last filter screen cleaning is relatively close to the current time point, and the filter screen cleaning is only needed to be carried out according to the first cycle rotation times. And under the condition that the time difference is greater than or equal to a second difference threshold, the time point of the last filter screen cleaning is relatively far from the current time point, and the first circulation rotation times are compensated through the circulation rotation times of the last filter screen cleaning, so that the target circulation rotation times are determined. And the air conditioner executes corresponding filter screen cleaning operation according to the current season and the target circulating rotation times.

As shown in connection with fig. 12, an embodiment of the present disclosure provides a method for cleaning a filter screen of an air conditioner, comprising:

s121, the air conditioner acquires the standby time of the air conditioner.

S122, the air conditioner judges whether the standby time is less than a standby time threshold. If not, S123 is performed. If yes, S124 is executed.

S123, detecting the light transmittance of the filter screen by the air conditioner.

S124, the air conditioner sets the time for cleaning the filter screen for the last time as a reference time.

S125, the air conditioner judges whether the difference value between the current time and the reference time is smaller than a difference value threshold value. If not, S123 is performed. If yes, S124 is executed.

S126, the air conditioner starts the cleaning assembly under the condition that the light transmittance is smaller than or equal to a set threshold value.

S127, the air conditioner controls the filter screen to circularly rotate.

By adopting the method for cleaning the filter screen of the air conditioner, which is provided by the embodiment of the disclosure, the energy consumption increase caused by frequent detection of the light transmittance can be reduced. Considering the use frequency of the air conditioner of a user, the air conditioner automatically detects the cleaning degree of the filter screen once under the condition that the air conditioner is not used for a continuous set time period of the user. For example, if the user does not turn on the air conditioner for 20 consecutive days, the air conditioner detects the degree of cleaning of the filter screen once. The standby cleaning filter screen of the air conditioner is used for realizing periodic cleaning, and meanwhile, the liquid circulation updating in the liquid storage equipment can be ensured. And under the condition that a user frequently uses the air conditioner, the dust of the filter screen is increased. Therefore, under the condition that the accumulated operation duration of the air conditioner reaches the difference threshold value, the cleaning degree of the filter screen is detected once. For example, every 100 hours the air conditioner is operated cumulatively, the air conditioner detects the degree of cleaning of the filter screen once. Meanwhile, the accumulated standby time is cleaned regularly, so that the situation that a user turns on the air conditioner once occasionally and then stands by for a long time is considered. Because the air quality in each area is different, the difference value threshold can be correspondingly increased under the condition that the light transmittance of the filter screen is continuously detected for multiple times without cleaning. The increasing mode can be that the time from the last filter screen cleaning and the accumulated air conditioner operation time between the last filter screen cleaning are set as a difference threshold value, and the difference threshold value can also be set by a user.

Therefore, the cleaning efficiency and the cleaning degree of the filter screen can be improved. Because substances such as lubricating oil exist in the air conditioner, impurities on the filter screen are difficult to remove, and the difficulty of cleaning can be reduced to a certain extent through high-temperature cleaning. Therefore, dense high-temperature and high-pressure liquid can be sprayed out through the self-heating function of the cleaning nozzle to clean the filter screen, and the efficiency of cleaning the filter screen is effectively improved. Meanwhile, the high-temperature wet hot water vapor generated by the high temperature can sterilize the filter screen.

Optionally, the opening duration of the air conditioner is obtained when the difference between the current time and the reference time of the air conditioner is smaller than the difference threshold. And under the condition that the opening time length is longer than or equal to the liquid collecting time length, the air conditioner controls the water pump to be opened, and the condensed water generated by the air conditioner is collected to the water storage tank. Therefore, condensed water can be collected through forward rotation of the water pump for cleaning the filter screen, and secondary utilization of energy is realized.

Optionally, the air conditioner controls the filter screen to rotate circularly, including: the air conditioner determines the target circulation rotation times of the filter screen corresponding to the light transmittance; the air conditioner controls the filter screen to circularly rotate according to the target circulation rotation times. In this way, the degree of cleanliness of the screen can be improved. The number of rotation times required by current cleaning is judged by detecting the light transmittance of the filter screen, so that the cleanliness of the filter screen after cleaning can be expected.

Optionally, after the filter screen cleaning process is finished, the air conditioner obtains the accumulated operation duration of the air conditioner. And under the condition that the accumulated operation time length reaches the recheck time length, the air conditioner detects the new light transmittance of the filter screen. And controlling the air conditioner to normally operate under the condition that the new light transmittance is larger than the set threshold value. In the case that the new light transmittance is less than or equal to the set threshold, the air conditioner sets the new light transmittance to the set threshold and reminds the user. Like this, through the air conditioner normal operating a period of time with the moisture on the filter screen weather, and then detect the luminousness of filter screen again, guarantee the accuracy that the luminousness detected.

Optionally, in the case of operation of the air conditioner, the ratio of water to the volume of the water storage tank is periodically detected. And prompting a user to fill water into the water storage tank under the condition that the proportion value is smaller than or equal to the proportion threshold value. In this way, a sufficient amount of water in the water storage tank can be ensured when the filter screen cleaning process is started.
